I see two options:

  *  you use a Session product
  
     From Zope 2.5 on, there is one
     bundled with Zope. I use FSSession for ages.

  *  You put the selected values into your "next" and "prev" URLs:
     similar to: "next?start=10&selected=4,7,8

     This requires that your values do not contain ','.
     You would need to use JavaScript to read the selected values
     and make the selected list (4,7,8) above.

     In the target page, you might need to split the string selected
     again to make a list.

     The session solution is easier...
